23 Claims. 1

This invention relates to improvements in weft replenishing looms and itis the general object of the invention to relate the bobbin magazine andthread control devices in such manner as to improve the operation of theloom with respect to the weft ends of the reserve bobbins and also thethreads of both the incoming and the outgoing bobbins which are involvedin a replenishing operation.

In the past it has been customary to provide a magazine in which thereserve bobbins have interfere with threads extending from the reservebobbins in the magazine to a thread holder located their'weft ends ledoutwardly away from the center of the loom to a thread holder andprovide additional means between the magazine and the fabric forremoving weft ends which are left incident to a replenishing operation.With such v an arrangement the thread of a freshly transerations.Furthermore, when the thread holder is at the outer end of the loom,some difliculty has been experienced in controlling the path of thethread or weft ends as the latter move downwardly in the magazine towardtransfer position. It is an important object of my present invention tolocate the thread holder between the magazine and the center of the loomand lead the weft ends from the bobbin tipsinwardly toward the threadholder. In this way the "thread of the incoming bobbin subsequent totransfer does not extend under the magazine and therefore cannotinterfere with subsequent transfers.

In weft replenishing looms as made heretofore it has been customary toprovide two different mechanisms, one to control the thread extendingfrom the incoming bobbin and the other to control the thread leading tthe outgoing bobbin. These two mechanisms are ordinarily on oppositesides of the magazine, the first being a thread between the magazine andthe center of the loom, and in order to avoid this interference it is afurther object of my present invention to provide means for supportingthe magazine at the outer end thereof, thereby leaving a freeuninterrupted space around the inner end of the magazine for the weftends of the bobbins in the magazine. In this connection I also providemeans for mounting the bobbin transferrer arm so that it is supportednear the outer end of the magazine where it will not interfere with theaforesaid weft ends. In order to effect correct threading of th shuttlesubsequent to a transfer operation it is desirable to locate the threadholder in a position somewhat to the rear of the lay when the latter ison front center. .When so located, however, the usual mechanismsemployed to place the thread of the outgoing bobbin for removal would beineffective, since such mechanisms ordinarily are located in front ofthe lay. It is a further object of my invention to provide threadcontrolling mechanism having an intake mouth or the like correctlylocated for the thread holding function thereof, and in addition providea thread placing mechanism which will move the thread of the outgoingbobbin upwardly and then rearwardly toward the intake mouth. This latterfeature of my invention lifts the outgoing thread over the back of theshuttle box to the aforesaid holder on the outer end of the magazine andthe second being .a thread remover on the inner end of the magazine. Itis another important object of my present invention to combine these twomechanisms and locate them adjacent to the inner end of the magazinebetween the latter and the center of the loom and in such aposition'that all the weftends of thereserve bobbins and the thread ofthe outgoing bobbin can be led tov a common point abovethe lay. As shownherein Lutillze'a pneumatic thread controlling device having a singleinlet mouth which receives all of the previously mentioned threads.

The usual magazine has a sup-porting foot secured to the. loom frame andconnected to the inner. end of the magazine, Such a'ifoot would singleintake mouth.

When pneumatic thread holders are used in the conventional positionbeyond the magazine it is frequently difficult to detach the thread of atransferred bobbin from the reserve bobbin weft ends entering the intakemouth so that it can'be drawn into the latter when out at the selvage.It is another feature of my invention to locate the intake mouth in suchposition that the weft ends of the reserve bobbins and the thread of thetransferred bobbin immediately after transfer apmouth but can enter thelatter freely for'eifective removal.

With these and other objects in view which will appear as thedescription proceeds, myin' ventionresides in the combination andarrangement of parts hereinafter described and set forth.

Referring'to Fig. 1, I have shown a loom frame I0, lay H, top shaft I2,lay connector I3, air pump Hi and a lever l5 operating the air pump bymeans of a connecting rod lfiattached to the lay. A pipe or air conduitl1 extends forwardly from the. pump and the latter operates during therearward strokes of the lay to create subatmospheric pressures withinthe conduit. The lay has a'shuttle box l8 to receive a shuttle S whichFig. 2, the upper end of which is provided with a hub 36 through whichpasses a tubular pivotal support 31 for the magazine. The tube 31 isclamped in fixed position on the hub 35 by bolts 38.

The magazine comprises inner and outer bobbin guiding plates 40 and 4|,respectively, connected together by tie rods 42 and rocking as carries aweft bobbin B. The lay reciprocates between front and back centerpositions in usual manner due to rotation of shaft l2, and. the shuttleis ordinarily picked when the lay is about atmthe mid point-in itsbackward stroke. The

.loom;frame [0 includes in .itsi'construction a breast beam I9 whichmaybe formed of angle iron or the like as suggested in the left handpart of Fig. 6.

A rocking mechanism. designated generally at has a:depending rod 2!controlled by mechaprovide :means for supporting the magazine 'Madjacent to the outer end thereof sothat there may be a free spacearoundthe. inner end of the magazine for threads which leadto thread controlmechanism located between the magazine and the center of the loom. Thepreviously mentioned breast-beam has a horizontal web 25 and a dependingweb '26 which isto the rear of. the web 25. In order to provide asupport for the magazine M I weld or otherwise secure. aplate 213 to thebreast beam l9 and secureito said plate a support or angle iron 28 whichin effect is a continuation of. the breast beam. Support ZS has adepending flange 29 and a horizontal top plate-3D. The support 28 ismade sufficiently strongto support the magazine and parts associatedtherewith and the vertical flange 29 is dis-:'

posed at the front of the support'for. reasons which will appearpresently.

Secured .to. the support '28 is: a stand: 35;.1see:

eitherof two operating positions.

a unit about the tubular support 37. The previously mentioned forwardlyextending rod 22 is connected as at 43 to the inner plate of themagazine so that the latter may be rocked to assume The inner plate isis provided with guideways 44 for the heads of reserve bobbins W, whilethe outer plate ti is provided with similar but narrower guideways 45for the tips of the bobbins W. The bobbins are arranged in two groups asindicated in Fig. 4 and feed downwardly by gravity toward transferposition, each stack having-its own transfer position and the magazinerocking so that the lowest bobbin of either stack maybe brought totransfer position.

The inner plate 40 of the magazinewmay be formed substantially as shownin Fig. 4. and has front and back smooth thread engaging-surfaces 5i]and 5!, respectively, which are connected: at their lower ends by athread engaging surface 52. These three surfaces 50, 5| and 52arecontinuous so that they offer no interruption'to the downwardmovement of the weft ends or threads T extending from the bobbins W.

It will be apparent from Fig. 3 that the threads T, instead of beingextended to the 'right'as'is usual, extend toward the left or.towardthecenter of the loom from the tip ends of the-bobbins and extendaround the surfaces 50 and-5! .to athread holder designated generally atH. This holder is of the pneumatic type and has: an intake mouth 53which opens toward the center of the loom.

The thread holder is formed preferably .of-a metal tube 55, the upperend of which is formed with a head 56 secured to the left end ofa-hollow tubular support 3'! by a set screw 51, asindicated in Fig. 2.The thread intake mouth 53 is aherefore in pneumatic communication withthetinterior of the tubular support 31. Thelatterfis extended beyond thehub 36 and has supported thereon a thread collector 5B, the. upperqend'of which is connected to the previously described conduit or pipe I1.The thread collectorv is a closed chamber and may be made according tomy aforesaid patent except for the manner. of its mounting. During eachbackward stroke of the lay subatmospheric pressures. are created withinthe thread collector. 58. and the tubular support 37, therefore creatingan inrush-of air a horizontal extension 6| fromuthe left end of whichasviewed in Fig. 2 depends a hammer-1B2- for engagement with the butt endsof the bobbins. A bobbin tip guide63 may also be extended downwardlyfrom the extension 6|. Theitransferrer armhas a hub 64' which issecured. to a shaft 65, and a "relatively heavy coil-lspring fifisurrounds the hub": 64 and has one end th'ereofoperatively engaging:the. transferrei armand has the'other end thereof held in fixed positionwith respect tothestand 35. -The latter is provided with a hub 81which.apr-ovides: ample support for-shaft 65. The latter'a'nd thetransferrer arm are'secured together and therefore move an-gularly inunison, andthe spring 66 acts in the usual manner j to'hold the:transferrer arm normally raisedasin'di-cated in Fig. 1.'

As viewed in 'Figs.-2 and 3 the shaft-fili'extends to the left fromthetransferrer arm a'nd passes through'and is rotatable in a bearing 19mounted on the support 28. latch arm 1| is secured to sha-ft 65 and'atransfer latch 12"is pivoted thereto as at 13. The latch is normallydown as shown in Fig; 4, :but can be raised by a lifter 14- When thetransferrer latch is lifted itwill be engaged by the hunter on theadvancinglay and moved forwardly or to the left as viewed in Fig. 5

to rock-shaft 85-in-a clockwise direction,therebyv depressingthetransferrer arm to effect transfer of-the bobbin under -'it.-

W l l At the'time of transfer a" thread T will extend from the shuttlein the box [8 toward the center of the loom; and in order to preventthis'thread from being drawn into' the warp shed-I provide means to liftitto a point adjacentthe intake mouth 53.- This mechanismcis shown inFig. '1; and comprises an" arm 88 secured to -the inner end of the shaft65' and extending rearwardly therefrom.- This arm is adapted forengagement with alever'8l' pivoted as at 82to a small stand- 83 fastenedpreferably to the -breast beam l5. Lever 8| has "an upper arm .84 forengagement with the'under'side of the arm 80, and has also a-lower arm85 which is pivoted as at'86 to a floating thread placer 81. The forwardend of the latter is provided with a roll 88 which slides ina cam groove89 formed in-a cam plate-9D secured'to the breast beam. The rear-end ofthe placer 81 may. be notched'as at 9|- to receive threadT" andlies-normally under the shuttle race 92, thelay-bei-ng provided with atransverse groove 93for this purpose. The groove 93 leads rearwardly toa vertical-box back 94 secured to the lay and formingpart of thepreviously described shuttl'ebox l8. A- spring'95 normally acts to holdthe placer 81in forward position. or in the full line position asshowninFig. 7.

At the time of atransferring operation arm 80 is depressed as shaft 65rocks and engages the upper arm 84 of lever'8l, rocking thelatter in acounter-clockwise direction as viewed-in Fig. 7 and moving thethreadplacer 81 rearwardly or to the right. This occurs. during thelatter part of the forward movement of the layon a replenishing beat of.the 'loom,-and thegroove 89 is so formed as to causethe .rear end ofthe thread placer 81 to traverse'the :path designated'by'dot' anddash-lin'e a in Fig. .7; This path of the rear I in 'the pneumatlcithread removing isystem land the'thread THwill be drawn into the mouth53, having previously been cut at a point adjacent to the shuttle eye bywell-known means not shown. The right end'of groove 89 is so formed thatthe notched end 8| of the thread placer 81 will move across the intakemouth 53 and hold the thread- T in position where it can be attracted bythe pneumatic thread holder during the first part of the upward movementof the transferrer arm as the lay begins to move rearwardly subsequentto completion of atransferring operation.

.Figs. 8 and 9 indicate diagrammatically the successive positions whichthe thread placer 81 and notch 91 move during a thread placingoperation. :During the first part of the operation the placer 81' passesthrough the positions vI,-II, and III, Fig.8, lifting the notch 9lalongthe front of box back 94. As the operation. continues through positionsIV, V and VI, Fig. 9, the notch rises over-and passes behind wall 94,ultimately reaching the position shown in dotted lines, Fig.7.

Under normal operation the lay reciprocates backwardly and forwardly andthe transferrer arm and latchx12 remain in idle position, thread placingoperation arm is up, and the thread placer 81 is down as in full lines,Fig. 7. Drafts of air are drawn intermittently into thethread holder Hto create tension in all of the weft ends or threads T extending fromthe reserve bobbins in themagazine. When atransferring operation isindicated by mechanism not shown herein but well understood, the lifter14 will raise the latch to operating position and as the lay advancesthe transferrer-arm will descend as already described, and arm 88 willalso be lowered. As a transferring operation proceeds the thread placerB1 is raised as already described and moves the thread T upwardly andthen rearwardly with respect to the box back 94 toward the intake mouth53. During transfer the bobbin W under the transferrer arm moves intoshuttle S and its thread descends. After. the transfer operation iscompleted the lay moves rearwardlyand the replenished shuttle is picked.The thread attached to the freshly inserted bobbin in. the

shuttle extends along the under surface 52 of the inside plate 40 andthen upwardly to the intake mouth. As the shuttle is picked it moves tothe left as viewed in Fig. 2 or in a general direction toward the.intake mouth and the slack thus created in the thread extending from thefresh bobbin is drawn into the thread holder. As the shuttle passes thethread holder thread begins to unwind from the bobbin and in doing sobecomes at leastpartially threaded in the trailing end of the shuttle.The-shuttle will be made in usual manner and will be provided with aselfthreading eye.

That part of the thread T which is adjacent to the selvage of the clothand was attached to the outgoing bobbin will extend upwardly from theselvage to the intake mouth and on the first beat-up after transfer'thethread T and the thread of the freshly transferred bobbin will bothextend from the selvage to the thread holder.

The usualform. of temple cutter, see Fig. 10, will serve to out thesethreads on some subsequent forward beat of the lay, whereupon they willboth be drawn into the thread holder and move through the tubularsupport 31 to the thread collector or accumulator 58, where they will beheld asdescribed in my Patent No. 2,199,353.

Fig.- 10 indicates diagrammatically an advantage growing. out of apneumatic. thread control system having a common mouthior the threads ofboth :the outgoing and the incoming bobbins.

Certain types of coarse weft are .hairy .and tendto cling to each otherdue to projecting fibers. When .weaving with such yarns the threads ofboththe outgoing and incoming bobbins may be matted together duringcutting .at the selvage and become in effect a single strand. When thethread remover and the thread holder have separate mouths as inconstructions heretofore proposed the ends of the strand are. pulled inoppo site directions by the remover and holder, and

neither .of these devices is able to .remove the strand from the loom.This condition cannot occur with my present .invention.v

Referring to Fig. 10, the .fabric F has extending therefrom one of thethreads .T which was connected .to the incoming bobbin and also thread Twhich was connected to the outgoing bobbin. The cutter mechanism Cclose-to the .selvage operates to cut these threads several picks aftertransfer, and during cutting both of these threads may be mattedtogether, as indicated at K. It will be understood from Fig. 10,however, even if these threads do cling together they will be drawn intothe intake mouth 53 and effectively removed from the loom because of thefact that a single intake mouth is provided for both threads.

Another feature of the invention will be apparent from a considerationof Figs. ,2 and 4. The weft ends of the front stack of bobbins enter andextend along .the right hand side of the intake mouth 53 as shown inFig. 4, while the weft ends of the rear stack of bobbins enter andextend along the back part of the mouth 53. When a bobbin is transferredfrom one or the other of the stacks, the shuttle S will be under themagazinc and to the right of the intake mouth 53 as viewed in Fig. '2,but during picking the shuttle will pass by the intake mouth to the leftand thereby draw its thread after it. Prior to picking the thread of thetransferred bobbin may be caught under one or another of the Weft endsof the group corresponding to it, and this thread along with the weftends will approach the intake mouth in a direction toward the fabric; or

fromthe outer end of the lay, but during-picking and due to motion ofthe shuttle the thread will be detached from its group of weft ends andhave its direction .of approach to the mouth reversed and extend towardthe intake mouth in a direction away from the fabric. When this threadis later cut at the selvage by the cutter C, Fig. 10, it can be drawnreadily into the intake mouth 53 because it is free from the weft endsin the mouth and will not be entangled by them.

From the foregoing it will be seen that I have provided an improved formof thread control for weft replenishing looms wherein the thread holderis located between the magazine and'the loom so that the thread of afreshly transferred bobbin will not extend under the magazine. This isof particular importance in multicolor weftre-- plenishing looms inwhich successive transfers can occur, the later transfer occurringbefore the thread-of an earlier transfer has been cut at the selvage andremoved :by the threadholder. ,It will also be seen that the threadextending from the thread holder lies along a path to the left of theshuttle boxes viewed in Figs. 2 and 3 and therefore will not becomeentangled with any parts of the shuttle box as the lay reciprocates.Furthermore, the transferrer arm is located adjacent to the outer end ofthe magazine and: therefore does not interfere with: the weft endsextending from thecre'serve bobbins-42o the *threadholder. The "threadplacer 81 operates not "only tolift the thread-of the outgoing bobbinbut also moves it "rearward'ly withrespect to the box back 94 towardthe'iintake mouthi53. This latter provision is desirable "because -it isof importance to have the thread Fholder located far enough behindthe-flay when the :latter is :onfront center position to effect atEleast partial self-threading of the-shuttle the pick immediatelyfollowing areplenishing operation; It :will also be noted that when theshuttle :is pickeditreverses the direction of approachof the weft .endof the transferred bobbin with :respect to the intake mouth 53, and indoing 'so detaches this thread from the ,gr'oup corresponding :toit sothat upon subsequent cutting. at the selvage the t-hread can be drawninto the month without interference by 'the other threads which approachthe mouthfrom a different -:d-irection.

Having thus :desoribedmy invention :it will .be seen thatchanges and-modificationsmay be :made therein by those skilled in the art withoutdeparting from the spirit and scope of the invention andI .do not wishto be limited to the details herein disclosed, ibut what I claim is:
